[英]Adobe Experience Manager (AEM), Dispatcher Invalidation Issue: DAM Assets Not Invalidated/Evicted From Cache but Pages Are

問題描述

我們有一個多站點 AEM 6.5.13 系統，前端帶有調度程序 4.3.4。

每個站點都有自己對應的 site[1-4]-dispatcher.any 文件（使用農場）。 每個站點的 /docroot 與每個站點的 VirtualHost 配置中聲明的內容相匹配。

還有一個包含以下內容的 invalidation_only.any 文件：

    /virtualhosts   { "invalidation_only" "dev.dispatcher.foo.com" }

    /filter   {
      /0001 { /type "deny"  /glob "*" }
      /0002 { /type "allow" /glob "*/content*" }

    /cache  {
       /docroot "/apps/cache/content"

invalidation_only.any 對應的 VirtualHost 有這個：


<VirtualHost *:80>
  ServerName dev.dispatcher.foo.com
  DocumentRoot /apps/cache/content

 <LocationMatch "^/dispatcher/invalidate.cache$">
      # domain A
      SetEnvIf CQ-Path ".*/content/site1/.*" FLUSH_HOST=dev.site1.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain B
      SetEnvIf CQ-Path ".*/content/site2/.*" FLUSH_HOST=dev.site2.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain C
      SetEnvIf CQ-Path ".*/content/site3/.*" FLUSH_HOST=dev.site3.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain D
      SetEnvIf CQ-Path ".*/content/site4/.*" FLUSH_HOST=dev.site4.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
 </LocationMatch>

 <LocationMatch "^/invalidation_only/dispatcher/invalidate.cache$">
      # domain A
      SetEnvIf CQ-Path ".*/content/site1/.*" FLUSH_HOST=dev.site1.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain B
      SetEnvIf CQ-Path ".*/content/site2/.*" FLUSH_HOST=dev.site2.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain C
      SetEnvIf CQ-Path ".*/content/site3/.*" FLUSH_HOST=dev.site3.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain D
      SetEnvIf CQ-Path ".*/content/site4/.*" FLUSH_HOST=dev.site4.foo.com
      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
 </LocationMatch>


</VirtualHost>

頁面正確失效，DAM資產沒有。

下面的 dispatcher.log 顯示了 test.jpg（site1 圖像）的激活。 我用更新的 test.jpg 圖像替換了現有的 test.jpg。

可以直接在發布服務器上看到新圖像，但通過調度程序，舊圖像仍然存在。 下面的 dispatcher.log 顯示的是 DELIVER 而不是 Evicted:(

我想知道以下是否是一個線索：

[Sat Aug 06 11:54:09 2022] [I] [pid 2132227:tid 139968756315904] Touched /apps/cache/content/.stat

/apps/cache/content是緩存根目錄，但它並不特定於有問題的 site1 test.jpg。 激活 site1 頁面時，會特別提到在相關的 site1 緩存路徑中創建的 .stat 文件。

此外，“找到的農場”與 site1 無關，它的頁面在哪里？！

我懷疑 invalidation_only VirtualHost 可能需要注意，和/或可能與復制代理相關，但我不確定從哪里開始。

刷新代理位於發布實例上。 它在作者上配置並激活。 我相信我們的配置基於以下說明：

https://experienceleague.adobe.com/docs/experience-manager-dispatcher/using/configuring/dispatcher-domains.html?lang=en

還有一些來自這里：

https://www.albinsblog.com/2016/06/dispatcher-cache-invalidation-for-multisite-configuration-AEM-CQ5.html

這是一個調度程序日志序列，顯示了對 site1 頁面的調用，對該頁面進行編輯並發布，再次調用現在編輯的頁面並顯示舊內容的成功驅逐/失效。

通過未編輯和緩存頁面的調度程序進行初始調用：

我想我明白了，這與相應的 invalidation_only VirtualHost 配置有關。 我需要為每個引用/dam/文件夾的站點添加一個附加行，無論出於何種原因，這不是預期的：

 <LocationMatch "^/dispatcher/invalidate.cache$">
      # domain A
      SetEnvIf CQ-Path ".*/content/site1/.*" FLUSH_HOST=prod.site1.foo.com

      RequestHeader set Host %{FLUSH_HOST}e env=FLUSH_HOST
      # domain B
      SetEnvIf CQ-Path ".*/content/site2/.*" FLUSH_HOST=prod.site2.foo.com
